hi all,

we have a package, vendor msi, that was incorrectly installed and now, we are not able to uninstall it, the error message is "this operation is only valid for installed products".

we cannot reinstall it because it tries first to uninstall what was wrongly install and it fails too.

but i can see the entry into add/remove programs.

how can i fix this crap?

any suggestions?

thanks!

- Load up the MSI and produce a report of what it intalls, file-wise and registry-wise.
- Build a script to remove the files and registry settings, being careful to only remove application-specific stuff.
- Add a command to the script (having made sure it actually deleted what you asked it to, of course, to run:

.....MSIZap T! [ProductCode]

to remove evrey last vestige of it from the machine.
